Hírilorn

Hírilorn, also known as Neldor, was an immense beech tree in Neldoreth in Doriath, next to Menegroth.

Hírilorn had three smooth and equally-sized trunks with no branches close to the ground. Between the three great trunks lay a small house where Thingol had Lúthien imprisoned to keep her from meeting with Beren. Beren later died in Lùthien's arms under it.

Etymology

The name Hírilorn consists of the Sindarin terms híril ("lady") and orn ("tree"), forming "Tree of the Lady".
